ELECTRICAL f APPARATUS FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Application filed June 27, 1918. ASerial No. 242,247.

` To all whom it may concew'z:

Be it known that I, .Iosnrrr Braun, a citizen of the United States, anda resident of the borough of Manhattan, in the city, county, and Stateof New York, have invented an Improvement in Electrical Apparatus forMotor-Vehicles, of which the following is a specification.

This invention relates to electrical apparatus, and with regard tocertain more specific features, to such as are employed in connectionwith motor vehicles for internal combustion engines.

One of the objects of the invention is to provide inexpensive andcompact electritrical apparatus for motor vehicles. Y

Another object is to provide an arrangement of apparatus ofthe abovetype which arrangement shall be convenient of application with respectto engines of various designs.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will belexemplified in the construction hereinafter set forth, rand the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one of various possibleembodiments of the several features of this invention, Figure 1 is anend view of a machine showing my invention, `Fig. 2 is a side viewthereof partly in section, only a fragment of the generator being shown.

Similar reference characters refer to similar parts throughout thedifferent views of the drawings.

Referring now to these drawings there is shown a generator 1 having ayoke 2 and an end head 3 closing one end of said yoke. Anydesired typeof regulation may be employed. The drawing shows by way of example alever L for manually adjusting the position of a third ybrush(notshown), which regulates the machine in a well known manner. The endhead 3 has a cylindrical Supporting portion 4 for bearing in whichVarmature shaft 6 turns. The bearing supporting portion V4, as shown,projects somewhat beyond the relatively fiat face of end head 3, and thebearing is preferably lubricated by oil to be fed through a passage 29formed integral with the end head and communicating by way of thebearing with either reservoir 30 or 31 cast integrally with the en dhead 3. As one of the two reservoirs is ordinarily Superfiuous,reservoir 31 may be plugged and reservoir 30 is shown in use havingtherein a wick 30 for feedlngoil to the bearing. The purpose of proyldmgfor two reservoirs although one only is 1n use will appear below.

Formed preferably integrally with end head 3 and symmetrically andintegrally with reservoirs '30 and 31, there is al casing 7 adapted toinclose preferably an automatic electromagnetic switch construction 8.Automatic switch 8 need not be described in detail vas its constructionis no part of my present invention. It may be simply noted that thefunction of this switch is to automatically form yan electricalconnection between the generator and a battery when the voltage of thegeneratorexceeds that of the battery by a substantial amount, this, forpurposes of charging the battery, and to automatically open suchconnection when the voltage of the battery substantially exceeds thatproduced by said generator for the purpose of preventing the batteryfromV discharging through the generator. Y The casing 7 as shown, ispreferably in the form of a rectangular box, having a base 9 preferablyformed integrally with and in the same plane as the flat portion of endhead 3. The sides 10, 11, 12 and 13 of said box are preferably formedintegrally with the base and with each other and extend at right anglesto said base and. away from said generator. One side of said box, in thedrawing, side 12, is preferably located in close proximity to bearingsupporting portion 4. It is to be understood that this box need not havethe shape set forth, but its sides may be, geometrically considered, ofany closed vcylindrical form. A cover 14 securedby screws 15 or the likepreferably closes said box or casing. On one side of said box ispreferably located a cover 16 in which a fuse (not ico shown) isdisposed. This fuse is prefercover 19, preferably made of rubber andhaving a main portion 2O directly covering said terminal and a tubularportion 21 through which a lead to the external circuit extends. rl`hedrawings show a single wire or grounded arrangement in which one.terminal (not shown) is connected to a metallic construction, such asthe engine, or the frame of the vehicle. lf my construction were to beadapted for a two wire system, each terminal would preferably beinclosed in a sep,- arate terminal cover 19. Formed preferably in thepart of the construction common to the flat portion of end head 3 andthe bottom 9 of the casing or box, there are preferably opeiiings 17through which the automatic switch 8 is electrically connected with thegenerator proper. The circuits are not described in detail as they areno part of my present invention.

The bearing supporting` portion 4, as shown in Fig. 2, is formed oflesser thick- `ness of metal near its free end, forming a pilot as shownat 32, the junction of pilot 32 and remaining part of the bearingsupporting portion 4 formingV a shoulder 33. Formed integrally with endhead 3 and bearing supporting portion 4 is. platform 34 havingpi'eferably tapped openings 35 and 36, the former adjacent the bearingsupporting portion and the latter adjacent the free end of saidplatform. An identical platform similarly perforated is formeddiametrically opposite the platform just de scribed, the two platformsbeing symmetrically disposed with respect to a diameter running thelength of the paper in Fig. 1.-

The tops of the platform are preferably in the same plane as shoulder33.

An ignition support 25 is preferably secured to the end hea-d by screwspassing through integral lugs on said Vsupport as shown at 23 and 24.The ignition housing consists preferably of a tubular portion 26telescoped overthe end of bearing supporting portion 4 as shown at 27and abutting shoulder 33. The lowerinost part of said tubular portion asshown in the drawing, is preferably flattened and'slightly spaced fromside 12 of the box or casing 7 as at 56. A second tubular Yportion 28 isshown somewhat to one side of the tubular portion 26 and at right anglesthereto, the openings in said tubes communicating as shown. The ignitionsupport is preferablycast fromk a single piece as shown inthe drawing.This ignition support as shown inthe drawings is preferably formedsymmetrically with respect toa bisecting plane parallel to the fiatsurface of end head 3. On each side of said support and in the plane ofthe corresponding end of tubular portion 26 there is a fiat surface 55of substantiallyA the form of platform 34.

Preferably keyed to an extension 3'( ofV shaft 6, there is a spiral gear38 preferably held against longitudinal movement with respect to saidextension by'a sleeve 39, one end of which abuts a washer 40 which inturn is held against shoulder'57 on the shaft, the spiral gear 38 beingyprevented from moving off the shaft by a nut 41 threaded to the end ofsaid shaft. The gear 38 is substantially concentric with the tubularportion 26 of the ignition support. Extending within tubular portion 28and preferably supported thereby to be driven by gear 38, there is anignition unit, only a fragment of which is showiion the drawing. Thisunit consists 0f a substantially vertical shaft 43 having on the lowerend thereof a spiral gear 44 adapted to mesh with gear 38 for thepurpose of driving shaft 43 from the generator shaft 6. Shaft 43 drivespreferably both a timer and a distributer, which latter elements are notshown as they are no part 0f my invention. Shaft 43 is preferablyinclosed in an insulating casing 42- fitting snugly within tubularportion 28 and having preferably au enlarged portion 45 resting on thefree end of said tubular portion. The casing 42, also, has preferably aperipheral groove as shown at 46 coacting with a setscrew 47 insertedfrom the exterior yof tubular portion 28, lthe set-screw effectivelypreventing the ignition unit from being bodily raised by the action ofgear 38,. The free end of the ignition support is preferably fashionedin the form of a clamp, there being a longitudinal split .48 between twointegral lugs 49 and 50 adapted to be drawn together by a bolt 51 forthe purpose of aiding in firmly maintaining the ignition unit inposition. A spring metal cover 52 preferably closes the opening intubular portion26 and is preferably secured by staking. The casting25,it is thus seen forms not only an ifriiition support, but a housing forthe ignition transmission.

Owing to the symmetrical form of the iglnition support and to thesymmetrical arrangement of the two platforms, one of which is shown at34, it is clear that the ignition support 25 may be secured either asshown in the dra-wing with lug 53 secured at 23 andvlug 54 at 35, orsaid supy port may be disposed symmetricallyto the position justdescribed b y being laid onits otherside with fiat surface 55 coveringplatform 34, luv 53 being secured at 36 and lug 54 at 36. y thisarrangement the ignition support may with equal facility beassembledwith the l ignition driving shaft 43,

.either toward the left of the generator shaft as shown in Fig.l 1, orsymmetrically to the `right of said shaft. ,Y

Y Owing to the great variety of designs of internal combustionengines'andto the great variety of arrangements of accessories thereof,it is clear that if the ignition drive were Vthe generator,yinterference with some part of the engine, or with one or more of itsaccessories would result unless ka great number of special designsweremade. By my invention', one design assembled in' either of 'two waysenables me to readily apply my apparatus to a engines. y

n engines employing magneto ignition relatively great variety of or incase it is not desired to operate the ignition from the generator, Isimply dispense with the ignition support 25 and the remaininglapparatus constitutes a complete .operative unit without any changewhatsoever. In this case, I am also enabled to dispose the housing ofthe generator in `any vangular position about its axis, so that thecasing 7 and itsinclosed apparatus 8 may readily be arranged withrespect to substantially any engine, to avoid interference,with otheraccessories or engine parts. In case the angle selected in any case issuch that reservoir 30 assumes substantially the position occupied bypassage 29, the functions of these two parts would be reversed, restionof the bearing regardless in what angular position the apparatus bemounted. There is always at least one passage in the upper half of thehead which serves for entry of oil and at least one reservoir in thelower half for storing the oil.

It will thus be seen that there is herein described apparatus in whichthe severalA features of this invention are embodied, and whichapparatus in its action attains the various objects of the invention andis well suited to meet the requirements of practical use.

As many changes could be made in tne above construction, and manyapparently widely different embodiments of this invention could be madewithout departing fromy the scopethereof, it is intended that all mattercontained Vin the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.
